Unfortunately this happens with most yellow roses when the weather gets hotter. In the cooler spring temps and early fall temps the yellow color is typically richer and lasts longer. You can also add some extra potassium to the soils as it will help build the root system and enhance the color in roses and other flowers. If you have never given your roses Kelp Meal, that is another thing you can give them that helps them fight stresses and disease, along with providing some great nutrients. The stronger the rosebush is, the brighter the bloom color and overal vigor of the rosebush.
